DESOATEN SC - Kusintha kwa Chikopa cha Chemistry Kufotokozera kwa malonda:
DESOATEN SC ndi mankhwala atsopano a chikopa opangidwa, opangidwa ndikugulitsidwa ndi fakitale yathu yonse ya mankhwala a chikopa. Katundu wapamwamba uyu amapereka maubwino osiyanasiyana owonjezera chikopa poyerekeza ndi mankhwala achikhalidwe a polima opaka utoto, kuphatikiza kukana madzi bwino, mphamvu zakuthupi, kudzaza chikopa bwino, komanso luso logwira bwino. DESOATEN SC yopangidwira makamaka makampani opanga utoto wa chikopa, sikuti ndi yosavuta kugwiritsa ntchito kokha komanso imathandizira kuyamwa... -
Njira yonse yopita kudziko lopanda 'formaldehyde' | Malangizo a zinthu za Decision's amino resin series
Zotsatira za free formaldehyde zomwe zimapangidwa panthawi yopaka utoto zatchulidwa ndi makampani opanga utoto ndi makasitomala zaka zoposa khumi zapitazo. Komabe, m'zaka zaposachedwapa nkhaniyi yatengedwa mozama ndi makampani opanga utoto.
Pa mafakitale akuluakulu ndi ang'onoang'ono opaka utoto, cholinga chakhala kuyesa kuchuluka kwa formaldehyde. Makampani ena opaka utoto amayesa chikopa chilichonse chomwe chapangidwa kumene kuti atsimikizire kuti zinthu zawo zili bwino.
Kwa anthu ambiri omwe amagwira ntchito yokonza zikopa, kudziwa momwe angachepetsere kuchuluka kwa formaldehyde yaulere m'chikopa kwafotokozedwa momveka bwino——

Chopangira utoto cha polymer chokhala ndi magwiridwe antchito apamwamba komanso kulemera kwa 'ma molekyulu' | Malangizo abwino kwambiri a chisankho cha malonda
kulemera kwa maselo a polima
Mu mankhwala a chikopa, funso limodzi lofunika kwambiri pankhani ya zinthu zopangidwa ndi polima ndilakuti, nthawi yomwe chinthucho chili ndi mamolekyulu ang'onoang'ono kapena macro.
Chifukwa pakati pa zinthu zopangidwa ndi polima, kulemera kwa mamolekyulu (kunena zoona, kulemera kwa mamolekyulu apakati. chinthu cha polima chimakhala ndi zinthu zazing'ono komanso zazikulu, motero polankhula za kulemera kwa mamolekyulu, nthawi zambiri chimatanthauza kulemera kwa mamolekyulu apakati.) ndi chimodzi mwa zinthu zofunika kwambiri zomwe chinthucho chimafunikira, chingakhudze kudzaza kwa chinthucho, kulowa kwake komanso chogwirira chofewa komanso cholimba cha chikopa chomwe chingapereke.Zachidziwikire, katundu womaliza wa chinthu cha polima umagwirizana ndi zinthu zosiyanasiyana monga polymerization, kutalika kwa unyolo, kapangidwe ka mankhwala, magwiridwe antchito, magulu okonda madzi, ndi zina zotero. Kulemera kwa mamolekyu sikungaganizidwe ngati chizindikiro chokha cha katundu wa chinthucho.
Kulemera kwa mamolekyu a zinthu zambiri zosungira ma polima pamsika ndi pafupifupi 20000 mpaka 100000 g/mol, ndipo katundu wa zinthu zomwe zili ndi kulemera kwa mamolekyu mkati mwa nthawiyi zimasonyeza kuti zili ndi katundu wofanana.Komabe, kulemera kwa mamolekyu a zinthu ziwiri za Decision kuli kunja kwa nthawiyi mosiyana.

Kuthamanga kwabwino kwambiri kwa kuwala | Malangizo abwino kwambiri a chisankho cha mankhwala a syntan
Nthawi zonse pamakhala zinthu zakale zomwe timapeza m'moyo wathu zomwe zimatipangitsa kumwetulira nthawi iliyonse tikaganizira za izo. Monga nsapato zoyera zachikopa zomwe zili mu kabati yanu ya nsapato.
Komabe, nthawi zina zimakuvutitsani kukumbukira kuti pakapita nthawi, nsapato zomwe mumakonda sizidzakhalanso zoyera komanso zonyezimira, ndipo pang'onopang'ono zimakhala zakale komanso zachikasu.
Tsopano tiyeni tidziwe chomwe chili kumbuyo kwa chikopa choyera——Mu 1911 AD Dr. Stiasny adapanga tannin yatsopano yopangidwa yomwe ingalowe m'malo mwa tannin ya masamba. Poyerekeza ndi tannin ya masamba, tannin yopangidwa ndi yophweka kupanga, ili ndi mphamvu yabwino yopaka utoto, mtundu wopepuka komanso yolowera bwino. Chifukwa chake yakhala yofunika kwambiri mumakampani opanga utoto pazaka zana zapitazi. Muukadaulo wamakono wopaka utoto, mtundu uwu wa tannin yopangidwa umagwiritsidwa ntchito pafupifupi pazinthu zonse.
Chifukwa cha kapangidwe kake kosiyana ndi kagwiritsidwe ntchito kake, nthawi zambiri amatchedwa tannin yopangidwa, tannin ya phenolic, tannin ya sulfonic, tannin yofalikira, ndi zina zotero. Chofala cha ma tannin awa ndichakuti monomer yawo nthawi zambiri imakhala ndi kapangidwe ka mankhwala a phenolic.

DESOATEN ARA Amphoteric Polymeric Tanning Agent ndi DESOATEN ARS Amphoteric Synthetic Tanning Agent | Malangizo Apamwamba a Chisankho
Pali munthu wotchedwa Wang Yangming mu Ufumu wa Ming. Pamene anali kutali ndi kachisi, anayambitsa sukulu ya maganizo; pamene anali mkulu wa makolo, anathandiza anthu ammudzi; pamene dziko linali pamavuto, anagwiritsa ntchito nzeru zake ndi kulimba mtima kwake kuti athetse kupandukako ndi kuteteza dzikolo kuti lisawonongeke ndi nkhondo yapachiweniweni. "Kukhazikitsa ubwino, ubwino ndi kulankhula si chisankho chachiwiri m'zaka zikwi zisanu zapitazi." Nzeru yaikulu ya Wang Yangming ili m'choonadi chakuti anali wachifundo kwambiri pamaso pa anthu abwino komanso wanzeru kwambiri pamaso pa zigawenga zachinyengo.
Dziko lapansi silili mbali imodzi, nthawi zambiri limakhala la hermaphroditic. Monga momwe zimakhalira ndi zinthu zopaka utoto pakati pa mankhwala a chikopa. Zinthu zopaka utoto za amphoteric ndi zinthu zopaka utoto zomwe zili ndi gulu la cationic ndi gulu la anionic mu kapangidwe ka mankhwala komweko - pamene pH ya dongosololi ndi mfundo yeniyeni ya isoelectric ya chinthu chopaka utoto. Chinthu chopaka utoto sichisonyeza mphamvu za cationic kapena anionic;
Pamene pH ya dongosolo ili pansi pa mfundo ya isoelectric, gulu la anionic la wothandizira kutenthetsa limatetezedwa ndipo limatenga khalidwe la cationic, ndipo mosemphanitsa. -
Pangani nkhani ya floater kukhala yofanana kwambiri, DESOATEN ACS | Malangizo Apamwamba a Chisankho
Ngati mukuyendetsa galimoto ku Xinjiang, tsatirani msewu waukulu wa Lianhuo kubwerera ku Urumqi, mutadutsa mlatho wa Guozigou, mudzadutsa mu ngalande yayitali, ndipo nthawi yomweyo mukatuluka mu ngalande - buluu lalikulu loyera bwino lidzakugwerani m'maso.
N’chifukwa chiyani timakonda nyanja? Mwina chifukwa chakuti pamwamba pake powala pa nyanjayi pamatithandiza kukhala bata, osati lolimba ngati madzi a m’chitsime kapena losokonezeka ngati mathithi, koma lodziletsa komanso losangalatsa, mogwirizana ndi kukongola kwa Kum’mawa kwa kudziletsa komanso kudziyang’ana.
Floater mwina ndi kalembedwe ka chikopa komwe kamasonyeza bwino kukongola kumeneku.
Floater ndi kalembedwe kofala kwambiri pa chikopa chifukwa cha mawonekedwe ake apadera, zomwe zimapangitsa kuti kalembedwe kake kakhale kosangalatsa komanso komasuka. Kamagwiritsidwa ntchito kwambiri mu nsapato wamba, nsapato zakunja ndi zikopa za sofa. Kamagwiritsidwanso ntchito kukongoletsa kalembedwe kake ndikuwonjezera mtundu wa chikopa, chifukwa kusweka kwake kumabisa kuwonongeka kwa chikopa.Koma choyandama bwino chimafunanso kwambiri chikopa choyambiriracho. Chimafuna kulinganiza bwino kwa buluu wonyowa, apo ayi chingayambitse mavuto osafanana. Komabe, ngakhale buluu wonyowa utakonzedwa bwino, kusiyana kwa zikopa zoyambirira za nyama, makamaka kusiyana kwakukulu kwa msana ndi mimba zam'mbali, kungapangitse kuti chikhale chovuta kwambiri pa kalembedwe ka choyandama. Chifukwa chake poyankha vutoli, gulu la Chisankho lapereka njira yatsopano yothetsera vutoli.
